Abstract

Objective: Our study aimed to investigate morphological changes using ultrasonic biomicroscopy (UBM) in the anterior segment after phakic pars plana vitrectomy (PPV) without tamponade. Methods: PPV surgery planned phakic patients were prospectively studied between October 2012 and March 2015. PPV patients who did not undergo cataract surgery and in whom intraocular tamponade was not used were included in the study. UBM measurements were taken a few days before and 10 days after the surgery. Through axial images of the anterior segment, the anterior chamber depth (ACD) and lens thickness (LT) were measured. Through the temporal quadrant over the radial cross-section images, the trabecular network-iris angle (TIA), ciliary body thickness (CBT), scleral thickness (ST), trabeculum-ciliary process's distance (T-CPD), iris-ciliary process's distance (I-CPD), and iris thickness (IT) were measured. Post- and preoperative values were statistically compared. Results: A total of 21 patients (14 females and 7 males) were included. A total of 16 left eye and 5 right eye surgeries were performed. With respect to the preoperative measurement, postoperative mean values of ACD, CBT1, CBT2, CBT Max, T-CPD significantly decreased (p=0.007, p=0.000, p=0.004, p=0.000, p=0.000, respectively), and LT and TIA values were found to be increased (0.001, and 0.001, respectively). Conclusion: PPV in phakic patients causes significant changes to the anterior segment parameters with ciliary body morphology.

Özet

Amaç: Tamponat kulanılmayan fakik pars plana vitrektomi (PPV) hastalarında, ultrasonik biomikroskop (UBM) kullanarak, operasyon sonrası ön segment morfolojisindeki değişimi araştırmak amaçlanmıştır. Yöntemler: Ekim 2012 ile Mart 2015 tarihleri arasında, PPV planlanan fakik hastalar prospektif olarak çalışmaya alındı. PPV operasyonunda, katarakt cerrahisi yapılmayan ve göz içi tamponat kullanılmayan hastalar çalışmaya alındı. UBM ölçümleri ameliyattan önce ve ameliyattan 10 gün sonra yapıldı. Ön segmentin aksiyel görüntüleri üzerinden; ön kamera derinliği (ÖKD), Lens kalınlığı (LK) ölçüldü. Temporal kadranda açının radyal kesit görüntü- leri üzerinden; trabekuler ağ-iris açısı (TİA), siliyer cisim kalınlığı (SCK), sklera kalınlığı (SK), trabeküler ağ-siliyer proçes mesafesi (T-SPM), iris-siliyer proçes mesafesi (İ-SPM) ve iris kalınlığı (İK) ölçüldü. Ameliyat öncesi değerleri ile ameliyat sonrası değerler istatistiksel olarak karşılaştırıldı. Bulgular: PPV operasyonu ile birlikte, katarakt operasyonu yapılmayan ve göz içi tamponat kullanılmayan, yaş ortalaması 60 olan, 16'sı sol göz, 5'i sağ göz, 14'ü bayan 7'si erkek toplam 21 hasta çalışmaya alındı. Ameliyat öncesine göre ameliyat sonrası ortalama ÖKD, SCK1, SCK2, SCK Max T-SPM istatistiksel olarak anlamlı derecede azalmış (sırasıyla; p=0,007, p=0,000, p=0,004, p=0,000, p=0,000), LT ve TİA artmış olarak saptandı (sırasıyla; 0,001, 0,001). Sonuç: Pars plana vitrektomi, fakik vakalarda, ön segment parametreleri ile birlikte siliyer cisim morfolojisinde belirgin değişime sebep olmaktadır.
